Question

BlackTom AI · Accepted Answer

In this question, we are comparing neurons and glial cells within the hippocampus and focusing on what each cell type can do.
Option 1: Propagate electrical impulses and perform synaptic transmission. Neurons are the primary excitable cells in the nervous system and are specialized to generate action potentials and communicate with other neurons via synapses. This capability is the hallmark that distinguishes neurons from most glial cells, making this statement accurate regarding neuronal function.
Option 2: Provide structural support to surrounding tissue. Glial cells, not neurons, are chiefly responsible for structural support, filling spaces, and maintaining the architecture of neural tissue. This statement describes glial roles rather than neuronal capabilities.
Option 3: Form the blood-brain barrier. While glial cells, particularly astrocytes, contribute to the maintenance and regulation of the blood-brain barrier, the barrier itself is formed primarily by endothelial cells with tight junctions and the surrounding glial endfeet. Neurons do not form the BBB, so this option misattributes a barrier-forming function to neurons.
Option 4: Remove cellular debris by phagocytosis. Phagocytic debris removal is a key function of microglia, which are a type of glial cell. Neurons do not perform phagocytosis to clear debris, so this option points to glial activity rather than neuronal activity.
Overall, the options contrast neuron-specific signaling capabilities with glial-supportive or glial-specific tasks, highlighting that propagation of electrical signals is a neuronal trait while the other functions align with glial roles.
